What do we do well, and what could we do better? Here are the highlights.

Horizontal hydraulic fractures in shales: are they real?

In ResFrac, we are always challenging ourselves—what should we be doing better? What new capabilities should we add to the simulator? One of our newest projects is adding horizontal fracture propagation. Under most conditions, hydraulic fractures form vertically, not laterally. However, in specific circumstances, horizontal fractures develop. Sometimes, they form in addition to vertical fractures, and sometimes, they form exclusively without any vertical fractures. Horizontal fracture propagation has not conventionally been included in commercial hydraulic fracturing simulators, but we think this is a capability well-worth developing.
